Abstract

Systems and methods for indicating conditions for the appropriate inflation and/or deflation of tires are disclosed. Some systems and methods include measuring a variable affecting the internal gas temperature of a tire, calculating by the processor an estimated internal gas temperature of a tire, and determining whether a tire is appropriate to inflate and/or deflate.

Claims

1. A method for indicating a tire condition comprising:

receiving, by a processor from a sensor, a variable affecting an internal gas temperature of a tire;

calculating, by the processor, an estimated internal gas temperature of the tire based on the variable;

determining, by the processor, whether the tire is appropriate to at least one of inflate or deflate, based on the estimated internal gas temperature of the tire;

displaying, on an output device, a value indicative of whether the tire is appropriate to at least one of inflate and deflate.

2. The method according to claim 1, wherein the variable affecting the internal gas temperature of the tire includes at least one of a distance traveled on a surface, a frictional coefficient of the surface, a brake temperature, and an ambient temperature.

3. The method according to claim 2, wherein the ambient temperature includes at least one of a preflight ambient temperature, an ambient flight temperature, and a post-flight ambient temperature.

4. The method according to claim 1, further comprising that the receiving, calculating, and determining are repeated until a determination that it is appropriate to at least one of inflate and deflate the tire is given.

5. The method according to claim 1, wherein the output device is in at least one of electrical communication and RF communication with the processor.
